chore(widget-builder): Remove old code

[narsaynorath]

Remove old widget builder code. Most of this is deletions, there are some parts where I relocated code or renamed files so the names made sense with the components that were leftover.

The structure of some of these files is a little weird at the moment, but I'll move them in another PR. I want this PR to mainly be deletions before I start restructuring the remaining code that is reused from the old widget builder.

Error: Unable to find an element with the text: Set thresholds. This could be because the text is broken up by multiple elements. In this case, you can provide a function for your text matcher to make your matcher more flexible.
